IMPROVEMENT 1N RoLLER'JAW-TEMPLE PoR Looms.'

The Schedule referred to in these Letters Patent and, making part .0f the same.

To all whom lit may concern.-

Beit known that I, WrLLIAM HENRY BURNS, of

Grafton, county of Worcester, Commonwealth ofMasf.

a roller jaw-temple, with concave grooves in the rolls for holding, sustaining, and extending the cloth as it passes over the breast-beam of the loom,-hereinafter more fully described.

It is simple in its constructiomand easily adjusted for any thickness of cloth; can be applied to all looms for weaving cloth. It will hold the cloth evenly, and does not tear or' deface the edges ofthe cloth.

In the drawings- Figure l represents a perspective view of my roller jaw-ternple. Screw h fastens the upper and lower` jaws together. Screw s adjusts the jaws to any thickness of cloth required. The slots I I are for boltig the4 temple to its position on the spring, which is on the breast-beam ofthe loom. .v l

Figure 2 represents the lower jaw, with the roller D-in its place; also, the raised lip G, which has teeth,

' into which the upper roll G matches when'adjusted,

as seen in fig. 1. l

Figure 3 represents a sectional view of the upper and lower jaws A and 'B, the -rollers C and D, with concave grooves, and the arbors E and F.

To enable others skilled in the art tornake and use my invention, I will proceed to describe its construction and operation.

I make the upper and lower jaws of cast-iron or other metals.

. My rollers, as seen i'n iig. 3, are turned with com cave grooves. other. Ihe roller I), in the lower jaw, is placed on an angle of oneeighth of an inch, more or less, which serves to incline the edges of the cloth outward.

Ooncave teeth are made in the lip G of the lower` jaw, which t into the concave grooves of the upperroll C,v as seen in fig'l', when broughtv together by means ofthe screws sh.

By this arrangement the cloth, when drawn through between the upper roll and the teeth, and then between the two grooved rollers, is held securely, and, as the rolls revolve on the arbors, the edges of the cloth are constantly working outward, and the cloth is Y thus held suspended as it is being woven.

The angle at which I place the roll, causes it to opcrate-on the cloth in its revolution something like a screw.

The roller D is mounted on its journal F, so that it may move laterally thereon, and toward the centre of, and overthe surface of the cloth, when the laybeats up and .slackens the cloth; but when the web is drawn taut, the rollers' are drawn together, and the roller I) slides outward and stretches the cloth widthwise.

I am aware that roller-temples have been made'with y teeth and spurs in various ways; but

What I claim, and desire to* secure by Letters Patent,as my invention, is viz:

The combination with the jaws A B of the groovcd Witnesses: l
